PROBLEM TO BE SOLVED: To provide a temperature measuring system and a temperature measuring method capable of improving the accuracy of body temperature measurement of an animal and realizing more reliable health management while suppressing deterioration of efficiency of temperature measuring work. . SOLUTION: A temperature measuring system 1 for measuring a body temperature of an animal in a non-contact manner includes a feeding sensor 14 capable of detecting a feeding of a calf C, and a thermography camera 3 capable of non-contact measuring a temperature distribution in a predetermined range. When the sucking of the calf C is detected by the sucking sensor 14 and a predetermined condition relating to the body temperature of the calf C is satisfied, the temperature distribution in a predetermined range including the eye part E of the calf C by the thermography camera 3. And a control unit 24 for measuring. [Selection diagram] Fig. 1【課題】測温作業の効率の悪化を抑制しつつ、動物の体温測定の正確性を向上させ、より信頼性の高い健康管理を実現することができる測温システム及び測温方法を提供すること。【解決手段】動物の体温を非接触で測定する測温システム１は、子牛Ｃの哺乳を検知可能な哺乳センサ１４と、非接触で所定の範囲の温度分布を測定可能なサーモグラフィカメラ３と、哺乳センサ１４により子牛Ｃの哺乳が検知され、子牛Ｃの体温に関係する所定の条件を満たしたときに、サーモグラフィカメラ３により子牛Ｃの眼部Ｅを含む所定の範囲の温度分布を測定させる制御部２４と、を備える。【選択図】図１
